Kyuden Mirai Transfers 28MW Solar to DBJ JV

• Kyuden Mirai Energy moves 28MW of solar assets into a DBJ-backed JV, Kyuden Mirai Solar LLC. With 12 projects and plans for FIP upgrades and battery storage, growth accelerates.

Kyuden Mirai Energy has transferred 28 MW of developed and owned solar power plants to a newly created joint venture with the Development Bank of Japan (DBJ). The assets were moved into the new entity, Kyuden Mirai Solar LLC, which now holds 12 solar projects in Japan ranging from 1 MW to 10.5 MW. The plants were commissioned between November 2010 and February 2017.

Kyuden Mirai Energy said its wholly owned subsidiary will handle operations and maintenance, aggregation and related services for the solar portfolio. The company also plans to acquire additional feed-in tariff (FIT) power stations, transition them to the feed-in premium (FIP) model, and add battery storage to enhance value.

What does Kyuden Mirai’s DBJ JV transfer enable for solar and battery upgrades?

• Creates a larger, financeable platform for scaling Kyuden Mirai’s solar portfolio under DBJ-backed governance and capital structure.
  
• Consolidates multiple operational solar sites (spanning 1 MW to 10.5 MW) into a single vehicle, simplifying future upgrades, refinancing, and commercial contracting.
  
• Enables systematic lifecycle management of existing assets by using a dedicated operating structure to oversee performance, maintenance planning, and output optimization across the portfolio.
  
• Supports aggregation of generation under one entity, which can improve offtake flexibility, reduce transaction costs, and strengthen market participation for both existing and future projects.
  
• Provides a clearer pathway to expand the pipeline by acquiring additional solar assets that can be transitioned to the newer feed-in premium (FIP) framework.
  
• Helps convert policy-driven revenue from FIT to FIP by enabling portfolio-level planning around dispatch/value maximization, compliance, and performance targets.
  
• Makes battery storage additions more feasible by establishing an upgrade-ready ownership and asset-management model that can pair storage with solar generation to improve dispatchability and utilization.
  
• Improves the investment case for storage by treating batteries as value-enhancing retrofit components across multiple sites rather than isolated projects.
• Strengthens revenue resilience by aligning solar operations with grid/market incentives that reward flexibility, peak shifting, and enhanced grid services.
